If you have AVI files and you have a DVD player that also plays divx/mpeg4 files, you can burn the files as data to a DVD. Otherwise, as LOCOENG stated above, you will need to convert the AVIs to be DVD compliant. Among the several programs that do this are Nerovision, ConvertXtoDVD, and DVD Flick.
